Twyneo is an investigational, antibiotic-free, fixed-dose combination of benzoyl peroxide, 3%, and tretinoin, 0.1%, cream for the treatment of acne vulgaris, using our proprietary drug-delivery technology. If approved, it has the potential to be the first acne treatment on the market that contains a fixed-dose combination of benzoyl peroxide and tretinoin. Tretinoin and benzoyl peroxide are each approved as single-agent products for the treatment of acne. They are frequently prescribed together, however, they have not yet been marketed as a combination product because benzoyl peroxide causes degradation of tretinoin when combined in the same formulation. In Twyneo, each ingredient is encapsulated in a silica shell, which is designed to release the ingredients slowly over time. Phase 3 studies are complete and we submitted our New Drug Application in October 2020.
